Birla Industrial & Technological Museum (BITM), a unit under National Council of Science Museums (NCSM), Ministry of Culture, Government of India, is at the Gurusaday Road, Kolkata. History Development of Birla Industrial & Technological Museum Birla Industrial & Technological Museum in Calcutta, inaugurated on May 2, 1959, under the governmental jurisdiction of the Council of Scientific & Industrial Research (CSIR), is commonly recognized as the precursor of India's science museum concept. Dr. Bidhan Chandra Roy, the then-Chief Minister of West Bengal, felt motivated to establish a similar establishment in India for citizen participation in science and technology following a tour of the Deutsches Museum in Munich. Pandit Jawaharlal Nehru, India's prime minister and entrepreneur Shri Ghanshyam Das Birla, supported and encouraged his concept and endeavors in this area. Birla Park, his magnificent mansion and surrounding block of land in Calcutta's affluent Ballygunge neighborhood, was bequeathed to the CSIR to establish an Industrial and Technological Museum. In 1956, Pandit Nehru got this wonderful donation from Shri G D Birla. The voyage from the government of India taking over Birla Park in 1956 to the inauguration of the Museum in 1959 was spectacular and demanding. The development of India's first scientific Museum under the aegis of the central government was the product of meticulous research and diligent work by the Museum's steering group, which was led by Dr. B C Roy himself and included several notable scientists, educators, and entrepreneurs. Prof. Humayun Kabir, the then union minister for scientific research and cultural affairs, inaugurated the Birla Industrial & Technological Museum to the world on May 2, 1959, in the presence of Dr. B C Roy, Prof. M S Thacker, the then Director-General of CSIR, and Shri Amalendu Bose, the BITM Planning Officer. Electricity, Petroleum, Nuclear Physics, Metallurgy of Iron, Steel, and Copper, Optics, Electronics, and Television were among the first exhibitions at BITM. Motive Power (1962), Communication (1963), Mining (1964), Popular Science (1965), Transport (1973), Underground Mock-up Coal Mine (1983), and Atom(1984) were among the numerous additional exhibits that sprung up as a result. However, since the public's expectations for BITM have changed, many of these old galleries have either been completely restored or replaced with modern exhibits. BITM has been providing in-museum instructional programs such as Common Seminars and Film Shows since its inception. Since 1965, Science Demonstration Lectures (SDL) for children remained a common element of BITM. BITM also launched
